Improvement in harvesters



. To @ZZ whom) ztmayconoern j Be itiknown that we, M. SHAWVER and S.Srrnwvnn, both of Bellefontaine, in the county of `Logan and `Stante ofOhio, have invented a new and Improved Baking Device for `Harvesters;and .n we do hereby declare thatthe n following isa full, clear, andexact description of thesame,reference being had to the accom,- panyingdrawings, making a part of this specif iication, in which-# :l

. h Thisinvention relates to an improved raking device forharvesters'of` that class which are provided with adjustable rake-teeth, and whichwork in slots inthe platform of the harvesterg. 1"

The object ofthe invention is to `obtain a raking device of thexclassspeciiied which may `be operated Iat `the will of the driver or attendiant,i and also be capable of being adjusted so that the sickle, whichisattached, asusual, to L the platform, maybe made to cut higher `orlower, as desired. n i y n To enable others skilled in the art to fullyunderstand andconstruct our` invention, we will proceed to describe it.`h

g form, as. shown in` Figs. y1 and 2. The inner side ofthe chamber E hasvertical slots c made in itwhich are in line with the slots b of theltop of the box or platform D. The slots c are `shown in Fig. l.

The bar E is connected toy the back a metal plate, F, secured to themain frame, and the outer end of said bar E is connected to asegment-plate, G, at the back Vof the main frame by means of a screw, c,which passes A through a curved slot, f, in said plate, as shown clearlyin Fig. 6. Bythis arrangement it will be seen thatthe box orplatformDmay be ad-l justed higher or lower, as desired, by simplyunscrewing the screw'e andsecuringthe outer end of the bar E'higher orlower to thesegy ment-plate G, the bar E working on the pivot d asacenter.

' H isa bar which is fitted to the outer or back side of the bar E, andis connected thereto by a guide, r/,the outer part of bar Hibeingsupported by a roller, h, which is fitted in a longitudinal groove,'z,in bar E. (See Fig. 5.)

therake-head. Underneath the rake-head g there is placed a slide, K, towhich Y the teeth j are Vattached by pivots 7c; This slide K has apinor'friction-roller, Z, secured to its under On the bottom of the box Dthere is a spring, m,`and a` spring, n, is also placed within the boxand attached to its backend or side, as

shown inFig. 2. The spring m is secured to the end'of a bar, o,lattached longitudinally toV the bttom of box D, and parallel withits-front and back sides.

On the back part of the main frame A there is placed a drum, L, whichhas a spiral spring, L', connected to it, and M is a cord attached todrum L and to the bar H.y The spring of 1the drum L has a tendency towind the cord upon the latter and draw the rake-head in the directionindicated by arrow l in Fig. 2.

N is a pinion, which is placed on the end of V a shaft, O, the front endof which has its bean l h of the mainframe A by a pivot, d, whichpasses-into i ing in a collar, I?, placed loosely on the axle C of thewheels. The shaft O has its outer bearing in a slide, p, which is fittedin the lower part of the plate F, (see Figs. 4 and 5,) and underneaththe outer part of said shaft O there is a lever, Q., having a cord, q,attached to it, which passes -up through the back part of the main frameand is connected to a treadle, R. (See Figs. 2 and 4.) The shaft O isrotated by gears r s from the axle C, and the pinion N on the back endof shaft O gears into the rack I of bar H when the back end of shaft Ois raised.

On the outer part of bar H there is placed a spring-stop, a, the use ofwhich will be presently shown, and on the main frame A there is atreadle, S, to the back end of which there is connected a lever, T.

The operation is as follows: As the machine is drawn along, the cutgrain falls onthe platform or upper surface: of the box D, `and therake-head J .is at the right-handend of the box D, within the chamber E,and is retained therein by the spring-stop u, which bears against theguide g, as shown in red in Fig. 2. Vhen the ral e-head J is within thechamber E, the teeth j are in a vertical position and in line with theslots c, as shown in Fig. l, the teeth being retained in that positionunder the action of the spring a on the slide K. "At any time when it isdesired to rake the cut Agrain from the platform the driver or attendantpresses down the front end of treadle S, and thereby causes the lever Tto force down the spring-stop u, free from the guide g, and allow thedrum L, under the action'of its spring, to draw the rake toward thedischarge end of the platform or box D, as 4indicated by arrow 1. Vhenthe grain is discharged from the platform or box D, the driver orattendant 'depresses the treadle R, andl thereby actuates the lever Q,which raises the back part of shaft O and causes its pinion N to engagewith rack I, and as the shaft O is rotated from the axle C, through themedium of the gearing r s, the pinionk N and rack I will throw therake-head back to its original position in the chamber E, the

spring m actuating the slide K and causing the teeth j of the rake topass down into the box D, the spring a raising the teeth as the rakeheadpasses into chamber E.

This arrangement of the rake-head, slotted platform, and adjustableteeth is not new, the same having been used and arranged precisely asherein shown and described; but we are not Letters Patent- 1. The drumL,)rovidedwithaspiral spring, L', and connected to the bar H, which isprovided with a spring-stop, a, and rack I, in con nection with theadjustable shaft O, provided with the pinion N, and operated as shown,and the treadles R S, arranged for actuating, respectively, the shaft Oand spring-stop a, substantially as and for the purpose set forth.

2. The manner of securing the bar E to the main frame A, as shown anddescribed-to wit, by means of the pivot d, slotted plate F, andset-screw e, whereby the platform, and colisequently the sickle, may bereadily adjusted higher or lower, as desired.
